Camellias naturally drop buds when they produce more than they have the energy to open. However, if you notice buds falling off continually, it may be due to either over watering or under watering.

Propagation of most species can be done through rooted cuttings. Choose healthy stems to take cuttings from the camellia shrub in late spring or early summer. From the stem tip, count back to the fifth or sixth leaf node and make a slanted cut directly behind the node. Remove all but the top two or three leaves.

Is mushroom compost good for camellias?

Mushroom compost use should be avoided where ericaceous plants such as rhododendrons, camellias, azaleas and heathers are being grown, as these plants need acidic growing conditions and are chalk-hating. Mushroom compost contains high levels of soluble salts, so it is better not used as a component in potting mixes.

Can you over water camellias?

If they are in a different aspect (not easterly) and they still don't open, it is because there is too much moisture in the buds from over-watering. In this case the buds will become quite large and the petals very shiny. Camellias do not need a lot of watering during winter.
